Answered: Size of RSA Keys?

[jackm]

Hello,

I am not a client yet, but I am interested.

Does Perfect-Privacy use 4096 RSA for it's OpenVPN and SSH?

If not, can it happen?

Hi,

for OpenVPN we use 4,096 bit public key encryption for the key exchange and AES-256 bit for traffic encryption. SSH2 tunnels are also using AES-256 bit for data encryption, the key exchange method used may depend on your settings though. You can find more information on our services on the page linked below.

Thanks! You have answered my question completely.

You can close the thread now if you wish.

No need to close any topic, others might still contribute. A continuing struggle

I don't see anything that would make such an attack infeasible against RSA with larger key size in principle. Or make it a cryptographic break of 1024-bit RSA for that matter

After a spell and lots of news later i would highly recommend to do it with 4096/sha512/self-signed. regards
